Problems solved by technology

[0003] However, at present, most artificial stone products use unsaturated polyester as the binder material, and there are certain air pollution in the process of production, processing and use, which does not meet the standards of environmentally friendly green building materials advocated by the state.
In addition, there is another important impact: this type of thermosetting composite material with a high content of unsaturated polyester (generally reaching more than 30%) is difficult to recycle after reaching its service life. Such materials are difficult to degrade, so with the end of life of such materials, a large amount of construction waste that is difficult to handle will be generated, which will affect the ecological environment.

Abstract

The invention discloses a preparation method of a degradable resin-based solid surface material. The method comprises the following steps of preparing white sugar syrup with a mass fraction, utilizing the white sugar syrup to soften the flexible unsaturated polyester resin, producing the unsaturated polyester resin with the water containing mass fraction of 30 percent, utilizing the unsaturated polyester resin as a binder, adding starch and other inorganic filler, vacuum discharging the bubbles through the mold casting under the effect of auxiliary ingredients, producing a rough board through medium-temperature maintenance, determining the thickness of the rough board, grinding the rough board, and polishing the rough board to finally obtain the degradable resin-based solid surface material. The production raw materials used in the method are cheap, the production process and the production equipment used in the traditional solid surface material production method of the prior art can be used, the cost is reduced, the odor is little, the toxic harm and the pollution can be greatly reduced from the production, machining and the production of the finished product, and after reaching the service life, the product produced through the method can be broken and buried in the soil so as to be rapidly degraded by microorganisms.

Description

technical field [0001] The invention belongs to the field of functional artificial stones, in particular to a method for preparing a degradable resin-based solid surface material. Background technique [0002] Solid surface material is a kind of artificial stone. Different types of artificial stone have different compositions. The main components are binders, fillers, pigments and curing agents. It is a new type of environmentally friendly composite material. Compared with traditional building materials such as stainless steel and ceramics, artificial stone not only has multiple functions, rich colors, but also a wider range of applications. Artificial stone is non-radioactive, easy to process, easy to renovate, impact-resistant, easy to maintain, seamless splicing, and various shapes, etc. It is widely used in shopping malls, hotels, office buildings, homes and other interior decoration places. favorite. [0003] However, at present, most artificial stone products use ...
